Is there really any point to increasing the pixel density of the iPad?
I have fairly good eyesight, and at a normal viewing distance (about two feet) I CAN'T SEE the pixels on my iPad 4. What's the point increasing density, creating more pixels that the GPU has to push (slowing things down) at this point?
Even with the iPad closer to my face I can barely see the pixels, and only if I really look for them. Text looks like a printed page. Images look like photographic prints. The current PPI is more than enough.
Because... If they slow it down, then they will be able to speed it up later and make you upgrade.
